T0 all 'whom it may concern: o,

,Be it known that'I, JAcoB M. OLINGER,'a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Trolleys, of which thefollowing is `a specification.

lMy invention relates to improvernents in tr'olleys. for electricrailways, particularlyZ to that type of the ,trolley employing a quicklyvdetacliable pole. i 4.

The object of my invention is to improve upon the connections heretoforeVemployedl for attaching the trolley-pole to the stand'` sothat theoperation'of removing and re-y ,placing the poles maybe more simply andeasily accomplishedand also to provide con-v nections which will be moresimple in con? struction','efi`ective in operation, andcheaper tomanufacture. *pf o.

The invention consists in 'the construc-l described and set forthin Inthe accoinpanying drawingsf-Figure `1 is a. front elevatim'ofy a trolleyembodying my improvements, the pole being shown broken away. Fig. 2 isa' rearV elevation off a portion of the same.` Fig. 3 is a front ele':vation of a portioniof the same, the trolley` pole and its clamp lshownin Fig. 1 being removed. Fig. 4: is a side elevation of a portion of thepole anditscl'amp.V Fig. 5 is l a Vertical section of some of the partsshown in: Fig. 1, the section beingV on the line 5- 5 With the swiveledsupport 'removed Fig.A 6 is a side elevation of the device with'the polebrokenaway. ig.` 7 is a transverse section on the line7- 7 of Fig. 5.Fig. 8 is a detail of a spring contact` between cer tain of the parts. j

Like parts are represented by :similar characters of referencethroughout the sev`` --4 'are projected below'the `pivotal connec' eralviews. p i j In the said V`ldrawings, 1 represents the,l part to whichthe4 trolley is connected such' as the roof of an electric car, vf2` isthe base ;of the trolley-stand'iipon which is swivelly imount'edftheusual standard ;3. 'The -sup-` porting arm of'the-trolley, representedby 4, has, its lower bifurcated end, 4a,-pi'votally connected to thestandard 3. through the me-` dium of the pivot pins 5 which extendthrough the bifurcated portion of'the. arm and also integrallyfformedbosses ionthe' stand. The bifurcated members of the arm form ;a' lock.

'5, which allows the'lip 22 to hook itself on the rear side of the armbelow the opening. The latch 2a is then pushed downwardly until thelooking flange 30 coincides withv :the opening 23,A whereupon'the springwill the -fiange 30 is removed from the opening and then pulls thelat'ch-plate up until the: flange 30 rests againstthev rear sideof'the': arm, where it will be he'ld bythe tension of 'the spring.By'then raising the'pole slightly, the projeection '21 and its lipf`22maybe removed from the lopening 23, the collar 12 rocking tov permit ofthis movement; the` opening 14 being slotted vto permit of this:

. Inv order that close contact may be made between the parts to preventarcing, there is riveted to the 'forward side of the arm a; springeplate81, preferably of phosphorbronze. The'upper end of this plate is bentrearwardly asindicated at 82 and thence downwardly asjindicated at 33;these parts; 32 and 33 being extended through the opening 28 so as' tolie along the lower edge ofthe opening and also 'along the rear side ofthe arm which is below the opening. Nor-. mally, the portion 83 projectsrearwardly atv a slight angle as shown in Fig.` SJ When the projection21l and its lip 22 are inserted in position, however, the portion willbe sprung against the wall of` the arm but its resiliency will causeitto lie atiall times against the lip 22 so that if the fit betweenthese'parts is not accurate, .there will nevertheless be a closeelectrical contact between them byv reason ofthis spring.` By thisconstruction it willibeseen that the pole may vbe quickly removed. andreplaced without the use of tools and without any undue exertion upon'the part of the operator, suchas is required where Springs.are-employed to hold the pole in locked position such Vas illus--trat'ed in my former gPatent No.,-840,649,' dated January 8th, 1907which employs av stif spring to hold the inter-engaging parts o in``engagement, 'whichspring must be com-v pressedwhen ampole'is removedor inserted, `and necessitates;considerable labor upon the part of theoperator; i i z Having thus descri'bed my' invention,-I cla'irn: o
